STRAP SLIDE BUCKLE.

Application filed October 15, 1923..

ing of the engaged parts for maintaining the same in their adjustedposition.

An object of the invention is to provide a flexible and durable strapbuckle of a single piece of material, interlaced with the strap andhaving finger tabs at its opposite end for conveniently gripping thebuckle for adjustment.

Other features and advantages of the invention will be more fully setforth in the description of the accompanying drawing, forming a part ofthis specification, and in the drawing like characters of referencedenote corresponding parts throughout the several views of which:

Fig. 1 is a side elevation of a head harness for use by footballplayers, with our improved quick adjustable buckle attached to the chinstrap.

Fig. 2 is an edge View of a chin strap with a modified form of buckle.

Fig. 3 is a face view of the buckle and at tached strap of the formshown in Fig. 2.

Fig. is a face View of the buckle and at tached strap of the form shownin Fig. 1.

Fig. 6 is a section on line 6, 6, Fig. 5.

The improved buckle is primarily adaptable for the fastening strap ofhead harness worn by football players, aviators, and motor-cyclists,requiring a quick and secure adjustment. It is desirable that a bucklefor such paraphernalia be flexible and non-metallic so as not to beobstructive or cause injury to the wearer and which will provide for aquick and secure strap adjustment either for release or tightening.

The buckle 1 in both forms illustrated comprises a piece of pliablematerial, as leather, preferably of oblong or rectangular dimensions,and of a thickness to give it the Serial No. 508,048.

proper tenacity for securely binding the strap or band 2, interlaced inthe buckle through parallel slits 8 and through the body of thematerial.

In the form shown in F 2, 3, an d buckle body is provided with thespaced parallel slits 3, each slit of a length slightly greater than thewidth of the strap or band 2, threaded through the slits and interlacedwith the cross bars Z), Z), formed by the slits. A free end of the strapas shown may be anchored or attached to the buckle by looping the strapabout one of the bars, as b, on gaged through the slits forming said barand fastening the free end of the strap upon it self by a fastener 5 orother fastening means.

The slits are out at an intermediate portion of the body leaving anextension from the slits at opposite ends of the buckle, longitudinally,providing tabs a-a for gripping the buckle at either end. The strap,from the buckle secured end, as in a chin strap for headgear, as a loop,extends through a slit in d, the

car covering extension 7 of the headgear 8,

as shown in Figs. 1 and 2, and thence in the form shown in Figs. 2 to 4inclusive, passes from the underside of the buckle through an end slit,to the forward side of the buckle over the bars 6, b, and through theslit at the opposite end of the series of slits to the underside of thebuckle. This presents the finger tabs c-a at the face side of the strapfor convenient gripping of the buckle to ad just the buckle upon, thestrap, to lengthen or shorten the strap reach as required.

'llhe buckle is of sufficient thickness to possess the requiredstability for frictionally gripping the strap between the opposite edgesof the adjoining transverse :-=houlder:i; or edge surfaces formed by theslit, which is further increased by a transverse contracting pull of thematerial created in offsetting the slit edge surfaces to the thicknessof the strap threaded through the slit. The looped end of the strappassing through several of the slits also augments the frictionalbinding of the parts. The strap being preferably an elastic webbingyields suiliciently to accommodate for any transverse folding or bending or longitudinal curvature the buckle may assume when the strap isextended over the curved or irregular surfaces, as in a chin band, forholding a head gear upon the head. of an individual, Without relaxationof the biting grip of the buckle upon the strap,

In the form shown in Figs. 1, 5, and 6, the buckle is provided With fourparallel slits 3,

providing three adjoining cross bars with WlllClltllQ strap isinterlaced, in which instance'thestrap'may be laced' assl'loiv'n, topresent the two opposite outerniostbarson' the underside of the strapand the intermediate bar on the face side. The strap coacting faces ofthe bars frictionally bear against the strap to resist its movement, andthe increased number of slits multiply the number of strapgrippingedgeaior'inoreaeing the buckle gripping function upon thestrap.- The luickle can be made of a leather stock, providing aflexiblenon-corrosive anddurable device, for the purposes intended.
